PSA weighed grades

in PSA Set Registry Forum
As we know, certain cards have a higher weight than others. Here is the question.. If One card has a weight of lets say 4 and another card has a weight of lets say 1 and the card weighted a 4 can be found in Psa 6 and the Card weighted 1 can be found in a psa7. Which of these card would raise my percentage better in the registry? What Im trying to say is should I be looking at the weight of a set also as as I buy psa graded cards?....Spazzy

    Card weighted 4 times grade of 6 = 24 points. Card weighted 1 time grade of 7 = 7 points. The lower grade card that is weighted higher is worth more than 3 of the higher grade/lower weight cards.
    Total of points divided by the set divisor = the set rating.
    Did I mention that I hate weighting and wish it would go away? If you need 3 cards you still need 3 cards, and often rarities are weighted much higher than easy to find stars in the set.

    The simplest way to look at it is to multiply the weight times the grade. The higher the result, the better. So, using your example:

    Weight of 4 x PSA 6 = 24
    Weight of 1 x PSA 7 = 7

    The PSA 6 will help you more than the PSA 7.

    To further illustrate... assume you are working on a five card set. Four of the cards have a weight of 1 and the last card has a weight of 4. The divisor for the set is 8 (1+1+1+1+4=8). The divisor is the sum of the weights for every card in the set.

    If you add a PSA 7 with a weight of one, your weighted GPA will be 7 and your set rating will be .875
    If you add a PSA 6 with a weight of four, your weighted GPA will be 6 and your set rating will be 3.00
    If you add both cards, your weighted GPA will be 6.2 and your set rating will be 3.875

    High weights make a huge difference in the set rating of smaller sets. The difference decreases as the number of cards in the set, and the set's divisor, increase.

    If the grades are the same, adding a card with a weight of 10 is the same as adding 10 cards with a weight of 1.

    Hope that helps!

    It does make sense. I dont think collectors take that in consideration sometimes. There are cards of semi stars that I noticed that have a higher weigh mark. A collector though, may not think that it would because of a cards regional appeal or scarce ness for some reason or another. Sometimes these cards are cheaper and they will help you more in your total score in the registry. Thanks....Spazzy

    this may be a dumb question but i will ask it anyway. can the weight of a particular card change over time for any reason? i have noticed in one of my registry sets that a couple cards are weighted very high (9) for no particular reason. i checked the population reports and there isnt a shortage of these cards and they arent major stars either. i dont get it sometimes.

    there are two measure - weighted GPA and set rating. the lower graded card will lower your weighted GPA if your current weighted GPA is above the grade of the card you add. but, the higher weighted card will increase your set rating more. My sets have a weighted GPA of 8 or higher, at least the sets I focus on. But, if you are going for a high set rating and are not concerned with what grade your set averages, then go for the lower grade but higher weighted cards.

    Coho-
    It's not about the pops, it's about the relative SMR value in PSA 8. As such, rarities (like the '58 Topps Herrer error, or the '58 Bell Brand Cimoli) and condition rarities (like the '62 Landrum) are weighted based on a hugely inaccurate SMR value.
    I've seen weights adjusted a few times, but it's not common in the sets I collect. Once it's down that tends to be it.

    I would focus on the MUCH in Grif's statement. Some times commons weighed 1 are more money and harder to find than the stars or minor stars which are in abundance.

    Doh!
    I had that backwards. It should read "Often rarites are much harder to find that higher weighted stars that are in abundance".

    I learned the hard way about weight and grade. Impossible to have a high registry basic mantle set without a high grade 52 topps. The 10 weight is too high, what about increasing weight on 57 and 58 topps mantle, now only 2 and three and for what you pay for a grade 9 the weight should be at least a 4.
